BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to lavatory devices and, in particular, relates to an anti-splash guard and deodorant pouch for urinals.

2. Description of the Related Art

Conventional deodorant urinal screens, which typically contain a deodorant block, fail to reliably prevent splashing of waste fluid, such as urine, from the interior region of urinals. Some conventional deodorant urinal screens have wide slotted openings that allow large amounts of waste fluid to strike the interior walls of the urinal through the wide slotted openings. This often results in splash back of the waste fluid outwardly from interior region of the urinal. For example, when waste fluid is projected into the urinal at high velocity, the waste fluid flows between the wide slotted openings, strikes the hard surface of the interior walls of the urinal, and splashes back outwardly from the interior region of the urinal. This generally causes exterior regions of the urinal to become wet with waste fluid. As a result, there currently exists a need to prevent splashing of waste fluid out of the interior region of the urinal.

In addition, the wide slotted openings of conventional deodorant urinal screens allow pieces of the deodorant material, such as a deodorant block, to be flushed down the drain of the urinal. Also, because the deodorant material is mostly exposed directly to the flow of flush water, urine, and any other substance placed in the urinal, the deodorant material may be quickly dissolved by the fluids. Accordingly, there is a need for improved apparatuses for holding a deodorant material in a urinal in order to increase a useful life of the deodorant material. There is also a need for improved structures for deodorant urinal screens that reduce the occurrence of splash back.

SUMMARY OF CERTAIN EMBODIMENTS OF THE INVENTION

In one embodiment, the present invention relates to an improved deodorant containment apparatus that is configured to increase the useful life of a deodorant material contained therein. In one embodiment, a deodorant pouch containing a deodorant material, such as a deodorant block, is placed in a urinal. The pouch may be sealed so that the deodorant material must be substantially dissolved in a fluid before it will pass through pores of the layers. Accordingly, the useful life of the deodorant material may be extended by preventing pieces from breaking off and entering the urinal drain. In addition, the pouch may comprise fibrous material that is configured to reduce the direct contact of urine and other fluids on the deodorant material. Because the deodorant material may be water soluble, by reducing the direct contact of fluid with the deodorant material, the life of the deodorant material may be extended.

In another embodiment, the present invention discloses systems and methods for reducing the occurrence of splash back that may occur when a fluid contacts a urinal. For example, an anti-splash guard may comprise a fibrous material configured to reduce splash back and may be configured for attachment to a back surface of a urinal.

In one aspect, a third portion 154 of the anti-splash guard 120 bends or folds along the length 130 thereof so as to accommodate the contour or curvature of the back wall 106 and bowl section 110 within the interior region 112 of the urinal 100. In another aspect, a fourth portion 156 of the anti-splash guard 120 bends or folds along the width 132 thereof so as to accommodate the contour or curvature of the bowl section 110 within the interior region 112 of the urinal 100.

Advantageously, the anti-splash guard 120 rests adjacent to the lip portion 111 of the bowl section 110 and adjacent to the back wall 106 of the urinal 100. In addition, the anti-splash guard 120 comprises fibrous strands 124 that form a porous mesh structure that is adapted to absorb the force of waste fluid being projected into the interior region 112 of the urinal 100. In one aspect, the anti-splash guard 120 substantially prevents the projected waste fluid form striking the underlying back wall 106 and bowl section 110 to thereby reduce splash back of waste fluid out of the interior region 112 of the urinal 100. Moreover, the absorption bias of the anti-splash guard 120 substantially reduces the occurrence of waste fluid splashing outwardly from the interior region 112 of the urinal 100. Beneficially, this increases the reliability and functional convenience of the anti-splash guard 120, which is advantageous in many circumstances.

Additionally, it should be appreciated by those skilled in the art that the anti-splash guard 120 of the present teachings can be contoured and/or adapted to fit various types of urinals. As illustrated in FIG. 4, these types of urinals may include an Innsbrook 0.5 Urinal 200, a Lynbrook 0.85 Urinal 202, a Trimbrook 0.85 Urinal 204, a Jetbrook 1.0 Urinal 206, a Washbrook 0.7 Urinal 208, an Allbrook 0.7 Urinal 210, a Stallbrook 0.7 Urinal 212, and/or a Maybrook 0.5 Urinal 214, as manufactured by American Standard of Piscataway, N.J. Moreover, it should also be appreciated by those skilled in the art that the anti-splash guard 120 may also be contoured and/or adapted to fit various other types of generally known lavatory devices and/or urinals including waterless urinals, dual-flush urinals, and high efficiency urinals without departing from the scope of the present teachings.

FIG. 5 provides a schematic exploded view of a pouch 500 configured for use in a urinal. As shown in FIG. 5, the pouch 500 generally includes a plurality of layers 502, 504, with a deodorizer 506 sandwiched therebetween. In one embodiment, each layer 502, 504 comprises a mesh material having fibrous strands, wherein the fibrous strands are formed so as to provide an anti-splash surface. The fibrous strands may comprise translucent or opaque materials formed of a semi-rigid or flexible material, such as polyethylene (PE), polypropylene (PP), polyvinyl-chloride (PVC), polyethylene-terephthalate (PET), various types of synthetic polyester meshes, etc. In another example, various floor buffing pads, such as Scotch-brite® manufactured by 3M company of St. Paul, Minn., may be adapted or sized to conform to the dimensional characteristics of the anti-splash layer as described herein. As also shown in FIG. 5, the layers 502, 504 are configured into a desired shape and size adapted for placement in a urinal. For example, in one embodiment each of the layers 502, 504 is substantially oval shaped. In one embodiment, the layers 502, 504 are attached by sewing an outer perimeter of the layers 502, 504 together using a suitable thread, such as a nylon or plastic thread. In other embodiments, the layers 502, 504 may be attached using other suitable means. In an advantageous embodiment, the layer 502, 504 of the pouch 500 are sealed so that the deodorizer 506 must be substantially dissolved in a fluid before it will pass through pores of the layers 502,504. In this way, the useful life of the deodorizer 506 may be extended by preventing pieces of the deodorizer from breaking off and entering the drain component 118 (FIG. 1), for example.

In addition, the use of a fibrous material for housing the deodorizer 506 reduces the direct contact of urine and other fluids on the deodorizer 506. Because the deodorizer 506 may be water soluble, by reducing the direct contact of fluid with the deodorizer 506, the life of the deodorizer 506 may be extended. Accordingly, the user of an appropriate fibrous material may increase the number of uses for the deodorizer 506.

In certain embodiments, the deodorizer 506 is a conventional restroom deodorant such as paradichlorobenzene (PARA) blocks or non-PARA blocks. Preferably, a deodorant in block form is sandwiched between two anti-splash mesh layers to provide a deodorizing effect to the mesh layers.

FIG. 6 illustrates a top view of the pouch 500 with the two mesh layers attached together, thereby sandwiching the deodorant block 506 therebetween. As shown in FIG. 6, the pouch 500 may have a generally round configuration and may be adapted for placement in a urinal.

FIG. 7 is a perspective view of a pouch 600 of another embodiment, illustrating the pouch 600 being attached to an attachment device 602. The attachment device 602 includes a suction cup 604 and a hook 606. When in use, the hook 606 is adapted to removably attach to the anti-splash guard 600 while the suction cup 604 is adapted to attach to a mounting surface such as a urinal. Thus, the pouch 600 may be replaced with a new pouch without removing the suction cup 604.

FIG. 8 is a perspective view of a urinal 800 having an anti-splash guard 820 and a pouch 500 placed therein. As illustrated in exemplary FIG. 8, the anti-splash guard 820 is mounted to the urinal 800 by means of a suction cup 810 and a hook 830. In an advantageous embodiment, the anti-splash guard 820 comprises a fibrous material having a density that is sufficiently low to prevent fluid contacting the anti-splash guard 820 from splashing outside of the urinal 800 and potentially onto the provider of the fluid. The exemplary anti-splash guard 820 is shaped to fit in the lower portion of the urinal without causing the guard 820 to fold.

In addition to the use of the anti-splash guard 820 in the urinal 800, a pouch 500 is placed in the bowel section 110 of the urinal 800. The pouch 500 advantageously houses a deodorizing material, such as a deodorant block or cake, and is also made of a fibrous material that reduces splash back from the surface of the pouch 500. Thus, the pouch provides a sanitizing function in the urinal 800, while also reducing splash back of fluid that contacts the pouch.

FIGS. 9A-9C are each views of an exemplary suction cup 904 that may be used to attach the anti-splash guard to a urinal. In particular, FIG. 9A is an elevated perspective view, FIG. 9B is a top view, and FIG. 9C is a side view, of the suction cup 904. The suction cup illustrated in FIGS. 9A-9C advantageously includes a lip 910 configured for use in removing the suction cup 910 from at attached surface. More specifically, a user may remove the suction cup 904 by grasping and pulling on the lip 910. Accordingly, time and effort required to remove the suction cup 904 may be reduced. In addition, the lip 910 provides a surface for grasping that reduces the risk of the user from touching a surface of the urinal.
